Question 937610
r = w/t
rates are additive:
r = 1/6 + 1/8
r = 0.29166666666
---
fraction of the job completed when both men work together for 3 days:
w = rt
w = 0.29166666666*3
w = 0.87499999998
---
fraction of the job remaining after both men work together for 3 days:
w = 1 - 0.87499999998
w = 0.125
---
time it will take Mr. Mann working alone to complete the remaining job:
t = w/r
t = 0.125/(1/6)
t = 0.75 days
